Application filed December 10, 1921.

To all 'whomfi' may concern Be it known that l, Ammer Coon, a citi Zenof the United States, and resident of Holyoke, in the county of Hampdenand State of Massachusetts, have invented certain new and usefulImprovements in Band- Tying Gauges, of which the following isaspeciiioation.

This invention relates to improvements in gauges for use in tyingdriving bands, oi' band-driven machines, with a regulated tension, theimproved device being especially adapted for use in tying the spindledriving bands olf spinning or twisting frames.

The invention has tor its object to provide a simple and durable deviceoit` the character set forth so constructed as tol decrease the laborand time required in tying bands.

In the drawings Fig. 1 is a side elevation of the device attached to aspindle bearing and spindle rail ready for use;

The device comprises an attachment and positioning member 1 which isslotted at its lower end and provided with lugs Q at the oppositevertical sides ot the slot. Between these lugs the lower end of aswinging tension-regulating member 3 is pivotally` held by a suitablepivot pin 4. A. horizontal bracket 5 is carried by the member 1 near itslower end, said bracket being on the op posite side of the member 1 fromthe tension member and adapted to extend under the spindle rail. l Thebracket 5 is formed with two lugs 6 which extend through the slot invthe member 1 and are secured in position by the pivot pin 4l, The lugs 6snugly lit the slot so that there can be no free up,-

and-down-movement of the bracket 5 indeversely as the diameter of thespindle beary ing, but has considerably greater length to facilitate itsengagement with the bearing when the device is in position for use.

The tension member 8 is formed with an extension or abutment 10 at itslower end which is adapted to engage the upper wall of the slot in themember 1 between the lugs 6 and to serve as a stop to limit the outwardand downward swinging movement of thev tension member away from thesupport or positioning member 1. rllhe tensionmember 3 is mounted on thepivot fl between the lugs 6, as clearly shown in Fig. 5. The tensionmember 3 is normally swung away from the support or positioning kmember1, to the limit of the movement permitted by the lug 10, by atension-regulating spring 11. One end of this spring is confined in a'socket 12 formed in the member 1, and the other end thereof is confinedin a socket 18 formed in an externally threaded plug or nut 14 screwedinto the outer end or a cylindrical bore or passage 15 extending throughextension member 3, said bore or passage being formed in a cylindricalenlargement 16 of said member. The nut 141 is provided with an interiorangular', longitudinally-entendA ing projection 17 which is adapted tobeen-4 gaged by a wrench for adjusting the nut to vary the tension ofthe spring 11. Said wrench must be inserted through an aperture in themember 1 and longitudinally through the spring and passage 15.

rlhe member 1 is provided intermediate its ends and en its inner face,that is to say, on the face which is placed next to the rail of thespinning frame, with a rotatable adapter 18. This adapter is providedwith straight bearing faces 19 and 20, said faces being at right anglesto each other and located different distances from the center of thepivot of the adapter. The adapter is formed with two stop shoulders 21and 22 which are designed to engage a stop in 23 mounted in themember 1. The adapter is also provided with two inwardly extending pins24, said pins being aligned with they face 19. The

aligning faces of said pin are arranged a suitable distance from thecenter of the pivot of the adapter7 for a purpose which will hereinafterappear. The band tying device is designed to be placed in position withthe outer edge of the rail of the spinning frame against the inner faceof the member 1; the under surface of the spinning rail engaging one ofthe bearing faces of the adapter. The purpose of providing the rotatableand adjustable device 1S is to adapt the device for use with spindlerails of different thick nesses. As shown in Fig. 6, the device is designed for use with a narrow or thin spindle rail. By rotating theadapter to the position indicated in dotted lines in Fig. 6, it will beadapted for use with a rail of greater thickness. By arranging thedevice as shown in Fig. 6, pins 24 may be brought into engagement withthe bottom of the rail if said rail is too thick to be engaged by thebear* ing surface 19, but is too thin to be engaged by the bearingsurface 20. By the use of this simple rotatable device the gauge may beadapted for use on almost any spindle rail now in use. The adapter ispivoted to the member 1 by means of a tubular rivet or pivot bolt 25;and this pivot is made tubular in order that a suitable key may bepassed there-through for the purpose of adjusting the nut 14. said pivotbeing substantially in line with the nut and with the bore 15 when thetension regulating member is in latched position, as will be hereinafterdescribed.

The member 1 is provided at its upper end with an integral bracket 26which is designed to project rearwardly or inwardly over the spindlerail when the device is in operative position. The bracket 26 is cutaway at its free end to form a notch or recess 27 adapted tobearvagainstthe spindle bearing 28 between the rail 9 and thespindlewhorl 29 and close to the said whorl. Secured to the upper surface ofthe bracket 26 is a plate 30. the free end of said plate being cut outor notched as at 31 to fit around and engage the spindle bearing 28,said notch being of such size as to accurately center the bracket 26 onthe spindle bearing directly below the spindle whorl, The plate issecured to the upper surface of the bracket 26 by screws 32; and itsfree end is formed with the upwardly and inwardly eX- tending guard lugs33 which fit over the lower flange of the whorl at diametricallyopposite points. The purpose of these guard lugs is to prevent the bandslipping down under the lwhorl during the tying operation and also whenthe tying band is released from the tying device and connected to thewhorl.' These guard fingers quite closely embrace the lower flange ofthe whorl and'A prevent the spindle being lifted in its bear ing so thatthe whorl is held in a substantially fixed vertical position withrespect to the tying device. The plate 30 is formed with longitudinalside flanges 34 which serve to stiften and straighten said plate.

rlhe upper surface of the bracket 26 is cut away on each side to formthe horizontal shoulders 35 directly below the plate 30. Secured to eachside of the bracket 26, by means of screws 36 and bearing on theshoulders 35 is a spring side arm 37. The free ends of these side armsare bent inwardly toward each other and then back upon thema selves toform triangular gripping jaws 33. These jaws are adapted to be forcedover the spindle bearing and to yieldingly engage it in order to holdthe tying device in position.

The member 3 is provided at its upper end with an arm 39 carrying at itsinner or free end an upwardly extending tying hook 40 around which thespindle driving band is passed in the operationl of tying the band, asindicated in Figs. 3 and 9. The free end of the arm 39 is beveledoutwardly and downwardly to form a cam surface 41 adapted to engage andride over the upper end of a vertically slidable latch 42 and to depresssaid latch against the pressure of springs43 when the member 3 is swungtoward member 1. The arm 39 is provided with a locking shoulder 44 whichis adapted to snap back of the latch bar 42 to lock the tension member 3against movement after the same is swung a predetermined distance towardthe spindle. The latch 42 is confined in a channel formed in the member1; and the springs 43 are mounted in sockets in said member. as shown inFig. 7. A pin 45 mounted in member 1 and engaging in a slot 46 in thelatch bar 42 serves to limit the movement of said bar. The latch bar 42at its lupper end is provided with two outwardly extending finger pieces47, one on each side of the arm 39. and said Enger pieces are adapted tobe depressed by the operator when he desires to release the tensionmember from the latch 42.

A. sheet metal cast-off angle lever, or dofer, 48 is pivoted by a pin 49to the upper end of the tension member. One arm 48a of said angle leverlies along the upper surface of the tension .member, while the otherextends downwardly and outwardly by the side of said lever. The. upperportion of said arm is cut out at its free end to provide Icast-off lugs50 which lie on either side of the tying bock 40. On the upper member48"L of the cast-off lever and on each side edge thereof is formed anupwardly extending outwardly projecting guide and retaining hook 51.These hooks are about midway the ends of the upper arm of the cast-offlever and are at each siderof the tying hook. The purpose of theseretaining and guiding books is to hold the band on the tying hook duringthe operation of pulling the ends of the band in `order to place theproper tension on the band. ln Fig. 8 the operation ot these retainingand guidinphoolzs l is illustrated. Spindle driving, bands are usuallyformed oit two strands twisted together. loop is 'formed at one end andat the other end the two strands are separated. One of 'these separatedends is passed through the said loop in one direction and the other `ispassed through the loop in the opposite direction when it is desired totie the band to the spindle` As shown in Fig. 8, the separated strands,after they have bee-n passed through the loop in the end of the band,are passed outwardly in opposite directions under the ruidi'ng andretainino hooks 51. It is manin b fest thatv these hooksserve to holdthe band down on the tyii'ig hook i0 and prevent it sliding` off saidhook during the operationv of tying' the band.

The operation of tying the band is as follows:

The lower end of the spindle bearing` 8 is engaged in the aperture '7 otthe bracket 5, and the member l is then swung upwardly to bring' itsinner face into engagement with the spindle rail 9 and to cause thespring` jaws 3S to engage `the spindle bearing 28. The recess 27 oi thebracket 26 and the recess 81 of the plate 30 receive the spindlebearing" and all of these parts serve to center 'the member 1 properlyyand to hold it against the spindley rail. The tension member 3 is freeof the latch; 42 and the spring 1l vtorces it forwardly, that is to say,toward the operator, and downwardly to the limit of its movement. Thelug,- 10 serves as a'limit stop. The spindle driving band is then passedaround the drive pulley or cylinder and on opposite sides of the spindlewhorl and its ends brought together in 'front ot the tying lug 40. Unestrand of the band is passed through the end loop of the band in onevdirection and the other strand is passed through said loop in theopposite direction.

These' separated strands are then passed laterally in opposite`directions under the rerlhe operator then pulls outwardly on the saidstrands. This causes the strands to -bear strongly against the hooks andcauses the loop end ot the band to engage the tying hook,A It will beunde-rstood that as strain is put on the separated strands they arepulled out or unravelled from the mainbody of the'band. This shortensthe band and puts a strain on the tying lug which throws the tensionmember upwardly and toward the spindle. It sometimes occurs that thelooped end ot the band will remain between the retaining lugs or hooksduringthe tying operation and will not entra-ne the tying; lug'. .lnthis event the strain of the strands on the retaining lugs will forcethe tension member upwardly to its latched position and the looped endof the band will engage the tying lug when the strain on the two strandsis relieved. The amtaintl of tension required to throw the tensionmember to its latched position will depend upon the adjust-ment of thespring il. TWhen theband has been contracted sufficiently to place thedesired amount ot tension on the tension member, said member will havebeen swung,r upwardly to its latched position, as illustrated in Fig. 3.This takes the tension of spring l1 off the band and the knot may thenbe completed by tying the two strandsI together as indicated in Fig. 9.The tying;a of the band is then completed and by forcing the the member3,'the'cast-ol lugs 50 will lift i the tied band off the tying lug andallow it to drop between the flanges of the spindle whorl. The gua-rdlugs 38 prevent the band drawingdown under the whorl during the tyingoperation and also prevent the whorl and spindle being' lifted duringthe tying operation. Tithout the guards 33 itr was found that sometimesduring the tyingr operation the band would slip under the whorl. Asordinarily mounted, the spindle has a slight vertical play and sometimesthe whorl and spindle were lifted during the tying operation and thisresulted in the band slipping under the whorl. p

When the tying operation is completed and the. band has been releasedJfrom the tying lug, the latch plate i2 is depressed and the tensionmember thereby released. rllhe device may then be quickly removed fromthe spindle. Of course, the device may be removed from the spindlewithout?releasing the tension member, but it is thefusual practicetorelease the tension member and to allow the liclr, produced by thetension member iiying outwardly` to release the device trom thespindle.`
